SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 585,431, dated June 29, 1897.

Application filed October 24, 1894. Serial No. 526,824. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS CORSOADEN, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shelf-Brackets, of which the following is a specification.

My invention relates to improvements in shelf-brackets; and the obj eot of myimprovement is to produce a shelf-bracket from sheet metal at a small cost and which at the same time shall be of superior strength.

In the accompanying drawings, Figure 1 is Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of one of the blanks from which my bracket is made. Fig. 4 is a plan view of one end of a blank for a modified form of my bracket. Fig. 5 is a side elevation of the outer end of a shelf plate as formed from two blanks like that shown in Fig. 4. Fig. 6 is a front elevation of the lower end of a wallplate formed in like manner, and Fig. 7 is a diagram showing the middle portion of two blanks and illustrating the manner of cutting them with but little or no waste of stock.

In the preferred form I cut out of sheet metal two such blanks as shown in Fig. 3 for each bracket. The blank thus shown is a right-angled piece somewhat like a carpenters square, with the outer end of each arm or member rounded or finished in any pleasing design. 111 the outer corner of this blank I cut out a right-angular notch 14, as shown in Figs. 3 and 7, of a depth equal to the width of the wall and shelf plate flanges 8 9, and I perforate said flanges to form screw-holes 10 at any desired points. These wall and shelf plate flanges are bent on the longitudinal lines 11, Fig. 3, so as to stand at right angles to the adjoining metal. The metal at the inner edge of the blank forms the continuous rib-plate 12, which extends in one solid piece inside of the angle formed by said wall and shelf plates, and it may have its inner edge eX- tending diagonally across the corner, as at 13. In Fig. 7 I show by full lines how the middle portion of two such blanks as seen in Fig. 3 may be out one from the other Without any The metal cut from the notch 14 at the outer corner being left will form a corresponding-shaped projection 15 at the inner corner of the blank. In order to form thediagonal edge 13, it is only necessary to cut off this projecting corner 15 on the broken line 16, Fig. 7, or, if desired, the inner edges of the rib-plate 12 may extend in straight lines until they meet, as indicated by the broken line 17, Fig. 7. In this case a piece of metal will be wasted that is the size and shape of the notch 14. As before stated, this piece may be left on the rib-plate entire or wholly or partially removed, and when partially removed it is obvious that it may be cut on any desired line within the limits of the piece out out to form the notch 14. After thus forming the parts in rights and lefts two of them are placed together and secured by rivets 18 or other suitable fastenings through the rib-plates.

Byforming thepartsinrightsandlefts I mean that the wall and shelf plate flanges of one blank shall be bent in one direction on the broken lines 11 andof the next blank in the opposite direction; but this is only necessary because I have shown the wall-plate a little longer than the shelf-plate. If desired, the wall and shelf plates may be of the same length, in which case the wall and shelf plate flanges may all be bent in the same direction.

In Figs. 4, 5, and 6 I have shown a modification for the end portion of the wall and shelf plates in which I notch or slit that edge of the blank which forms the rib-plate, whereby said plate terminates in said notch and the line of longitudinal bend for the wall or shelf plate flanges 88 and 99 stops short of the end, as shown by line 111, Fig. 4. Then when two of these parts are put together the flat unfolded end portions 19 are lapped one over the other, as shown in Fig. 5, and substantially as patented to me March 13, 1894, in Patent No. 516,475, but this manner of finishing the ends makes no difference with the construction of the rest of the bracket.

I have shown my bracket without any brace, and for the smaller sizes it will be of ample strength without anything more than What I have shown. If desired, however, the larger sizes may be provided with any ordinary brace secured in any ordinary manner, the presence or absence of said brace not in any way changing the construction of the bracket herein described.

By my improvement the bends for the Wall and shelf flanges are easily made, and the rib-plates are neither cut apart nor put together, whereby they are not only cheaply produced, but are of superior strength.

I claim as my invention As a new article of manufacture the hereindescribed bracket, consisting of a pair of separate1y-constructed right and left hand parts, both parts consisting of asolid right-angular rib-plate with Wall and shelf plate flanges along the outer edge of each arm of said ribplates, the flanges on one of said parts being bent to the left and those of the other one of said parts being bent to the right, the said two parts being placed side by side With the broad sides of said two rib-plates resting flatly against each other and firmly united by mechanioal fastenings, substantially as described.
